" Application filed April 6;

The principal object oftlie prcsent invention new provision ina ventilator, used 111 connection withwindows, of disinfecting means to-act upon the-incomingair to disinfect'andpurit'y the same:

Another object of the invention is the pro vision' of" anim-proved window ventilator.

WVith the above general objects in view and others that will app-car as the nature of the invention is better understood, the same consists in the novel construction, combination andarrangement of parts hereinafter more fully described, illustrated in the accompanyin g drawing and pointed out in the a ngended' claim.

In the drawing forming part of this application, and in which like designating characters refer to corresponding parts throughout the several views, 7

Fig.1 is a perspective view of the lower part of the window showing the application of the present invention;

Fig. 2 is a transverse cross-sectional view; and

Fig. 3 is an elevational perspective view of the central portion of the device illustrating means for locking two sections of the ventila- Referring to the drawing in detail there is shown therein a window of the usual construction including sill 10, frame 11 and horizontal lower sash'bar 12 of the lower portion of the window. The ventilator embodies two sections, each comprising a rectangular frame, generally I indicated. by 13, and including rectangular section 14 and a surrounding side wall 15, the latter being integrally formed with said section 14. Thus the frame 13 will assume a box-like formation. The opening effected by said frame sect-ion 1 1 is covered by mesh 16 which prevents the dust from coming into the dwelling throughthe window. An L-shaped tube 17 is positioned within said frame 13, and in the operative position of the ventilator in the window, said L-shaped tube 17 rests within the corner of each section of the ventilator, at the lower portion thereof, while the shorter leg por: tion of the tube rests within the corner of one of the upright sides of each of the frames 13, as clearly seen on Fig. 1. Each of said tubes 17 is provided with a plurality of apertures or openings'18 arran ed in a row at, the upper portion of each of said tubes. Said tubes are adapted to be filled with cotton or other 1928"; Serial Ni). 267.8173

absorbent-- material 19 to absorb liquid dis-- infectant whieh' is supplied to the tube through the upright shorterportion thereof, and which is adapted to evaporatethrough openings 18 and thus to act upon the incoming air which enters the dwelling through mesh 16 and thus-to purify and disinfect t same.

Rigidly fixed to the outer face of frame 13 of one sectionof the ventilator is an angle plate 20 for the purpose of contacting with the outer face of the window sash bar 12 for holding the ventilator in position within the window. A similar plate 21 is attached to the underface of the side wall 15 of the other section'of the ventilator, one portion of said latter plate projecting upwardly'for contacting with the inner face of the window sash bar 12 for preventing the outer shifting movement of the ventilator when the same;

is in its operative position in the window illustrated on Fig. 1. r

The two sections of the ventilator hereinabove described are connected through the medium of a locking means which includes a plate 22 aiiixed at the inner face of the shortvertical section of side wall 15 and is mounted thereuponby means of rivet 23. Said plate 22 projects beyond the free edge of said side wall 15' and at its upper edge is provided with a slit or recess 24:.

The adjacent section of the side wall 15 of the other section of the ventilator carries locking plate 25, which by its one end is af fixed at the inner face of said adjacent portion of side wall 15 of the other section of the ventilator. Said plate 25 is bent at substantially right angle towards plate 22, the end of saidplate 25 beingslit on horizontal line, the lower portion of said slit end of said plate 25 affecting bolt 26 which is receivable, within recess 2 of plate 22. The upper'portion of said slit end of plate 25 is bent upon the "innerfface of" the adjacent shorter portion of the side wall 15, as at 27,

and in conjunction with the remaining portions of said plate 25 affects a Ushaped hand adapted to grip the two adjacent contacting short portions of side wall 15 of eachsection of the ventilator, preventing the longitudi nal disengagement of said two sections;

From the construction described and clearly shown on Fig. 3, bolt 26' cooperating with plate'22 prevents the lateral shifting movement ofthe-respective sections of theventi lator; To disengage the two sections of the ventilator thesection upon which plate 25 is mounted is shifted upwardly until bolt 26 is brought out from within recess 22. Thereupon said first mentioned section of the ventilator will become disconnected from the other section.

The advantage of having the hereinabov'e described ventilator made in two sections resides in the fact that the two sections may be easily transported and furthermore said sections may be made in various lengths, which, in combination, may fit various widths of windows.

lVhile there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made-therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

In, a window ventilator having a plurality of sections, said sections including side walls, inter-locking means between the adjacent sections comprising a U-shaped plate mount ed upon one section'and engaging the adjacent walls of said sections, a bolt projecting from said U-shaped plate, and a plate mounted upon the other section, said latter plate having a recess for receiving said bolt.

In testimony whereof I afiiX my signature.
